Which Animals Have Blue Blood?

Invertebrates with Blue Blood

• Octopuses, tarantulas, scorpions, and horseshoe crabs have blue blood, containing copper-rich hemocyanin, which serves as an oxygen transporter but is less efficient than hemoglobin.
• Crustaceans, squid, and some octopuses have blue blood due to the presence of copper pigment hemocyanin, unlike iron-rich hemoglobin found in humans.
• Some tardigrades are incredibly resilient, surviving harsh conditions that would be fatal to most other life forms.

Vampire Squid and Octopus Unique Blood Characteristics

• Vampire squid’s blue blood contains hemocyanin, which binds and transports oxygen more efficiently than other cephalopods, supporting their survival in deep-sea environments.
• Octopuses have three hearts to compensate for the less efficient oxygen transport of hemocyanin, demonstrating extraordinary adaptations for their survival.

Human Blood Myth

• Human blood is always red; the bluish color of veins under the skin is an optical illusion, and blood does not change color due to oxygen depletion.
